Abstract
The invention relates to compound pesticide and fungicide. The pesticide and fungicide comprises dinotefuran and tebuconazole which are utilized as active components. The compound pesticide and fungicide is efficient and low in toxicity, has excellent insecticide and sterilization activities to wheat aphid, damping off and banded sclerotial blight, generation of drug resistance is delayed while dosage of the pesticide and fungicide is reduced, the duration is prolonged, the pollution to the environment is reduced, and the plant safety is not hazarded.
Description
Technical field
The invention belongs to the pesticide seed coating field, is the composite insecticidal bactericide take MTI-446 and Tebuconazole as active ingredient specifically.
Technical background
MTI-446 (dinotefuran) is the novel nicotinamide insecticide that Mitsui East Asia KCC develops and went on the market in 2002.It is the unique not chloride atom of bases insecticide and aromatic ring. be referred to as third generation nicotinic insecticide, have super-high-efficient, wide spectrum, consumption is few, toxicity is low (preparation little poison level), lasting medicine, to crop without poisoning, use the advantage such as safety.This medicament have tag, strong, the quick-acting height of absorption in stomach toxicity and the root, the characteristics such as the lasting period is long, insecticidal spectrum is wide, and sucking insect had excellent preventive effect, and namely shown very high insecticidal activity at very low dosage.Be mainly used in preventing and treating aphid, leafhopper, plant hopper, aphid, aleyrodid and resistant strain thereof on the various crop such as wheat, wheat, cotton, vegetables, fruit tree, tobacco leaf, simultaneously coleoptera, diptera and Lepidoptera, diptera, beetle order and total wing order insect are had efficiently, and to blattaria, have efficiently from sanitary insect pests such as ant, houseflies.
Tebuconazole (Tebuconazole) belongs to triazole bactericidal agent, the sterol demethylation inhibitor, and the disease that fungi especially Basidiomycota and Ascomycota are caused has protection and the therapeutic action of broad spectrum activity.Destroy and stop the biosynthesis of the cell membrane important composition composition ergosterol of germ, cause cell membrane not form, make germ dead.Have this medicine of interior suction, protection and therapeutic activity and can effectively prevent and treat the disease that sac fungi, basidiomycetes and imperfect fungus cause, especially basidiomycetes and the microbial disease of ascus such as powdery mildew, rust, scab, brown spot, anthracnose, banded sclerotial blight, false smut etc. are had preferably preventive and therapeutic action.
Wheat aphid, damping off are main insect and the diseases of Wheat Seedling, and all there is generation in wheat in all parts of the country district, and wheat aphid is sucked the juice of wheat leaf, stem, tender fringe with adult, nymph.Just being yellow stigma by harm, is streak afterwards, and withered, whole strain becomes till death withered.Not only affect breathing and the photosynthesis of plant after the wheat aphid harm, the viral disease that also can spread disease causes wheat yield and even total crop failure.
The wheat damping off claims again full rot, is a kind of soil-borne disease, and the soil is porous for general soil, fertility is low, and the basic soil morbidity is heavier.The soil humidity is conducive to disease generation and expansion.Full rot is a kind of root disease, only infects Mai Gen and basal part of stem 1-2 joint.Seedling stage, diseased plant was short and small, bottom Huang Yeduo, and stem becomes grey black in seminal root and the ground, and it is withered to cause wheat seeding to connect leaf when serious.Show the jaundice of disease seedling radical leaves on the ground, lobus cardiacus is involute, the minimizing of tillering, and it is weak to grow, dead when serious.The postponement of turning green of sick seedling, short and small sparse, the root blackening increases the weight of.
Summary of the invention
The object of the invention is to carry out rational mixture by MTI-446 and Tebuconazole, solution repeatedly repeats dispenser when plant disease and insect pest occur the same period make troubles to the user, and repeating the adverse effects such as poisoning that dispenser causes, this composite insecticidal bactericide is mainly used in preventing and treating wheat aphid, wheat damping off and banded sclerotial blight.
The present invention is a kind of with MTI-446 and the composite insecticidal bactericide that forms of Tebuconazole, field efficacy experiment by the experiment of formula indoor screening toxicity test, mixture, clear and definite two kinds rational formula, the mass ratio that is MTI-446 and Tebuconazole is 50:1～1:10, all the other are to allow in the agricultural chemicals to use and the acceptable auxiliary element, under better formula, Wheat Seedling aphid and wheat damping-off control are reached preferably effect.
The present composition can be prepared into by known method any one formulation that is fit to agricultural use, and reasonable formulation is kind of a clothing agent.
The auxiliary agent that uses in the composition of the present invention comprises that wetting agent, dispersant, thickener, film forming agent and other are of value to the known substance of active ingredient stable and drug effect performance in preparation, all be various compositions commonly used in the pesticidal preparations or that permission is used, be not particularly limited, concrete composition and consumption require to determine by test according to prescription.
Composite insecticidal bactericide of the present invention can be used for the control of Wheat Seedling aphid, damping off, banded sclerotial blight, especially wheat aphid and damping off is had good preventive effect.
The present invention has following remarkable result associating advantage: after one, MTI-446 and Tebuconazole are mixed, enlarged prevention and treatment range, Wheat Seedling insect pest and disease are had dual control action; Two, be used for wheat seed dressing after MTI-446 and Tebuconazole are mixed, reduced drug cost, reduced peasant's labour intensity; Three, increased the lasting period after MTI-446 and Tebuconazole are mixed, four, after MTI-446 and Tebuconazole be mixed, improved the quality of wheat seedling.
The applicant has carried out the prescription screening study to MTI-446 and Tebuconazole, specifically tests situation and the result is as follows:
Experimental pharmacy adopts the former medicine of 95% MTI-446 and 95% Original Tebuconazole, is mixed with required preparation by the inventor, and according to the matched proportion density of setting, it is for subsequent use to be mixed with the desired concn liquid.
The processing of seed: choose the rice paddy seed of particle homogeneous, for subsequent use after with the surface of the seed dressing with liquid respectively.
Pot-culture method is adopted in experiment.Wheat damping off: first with behind the Dressing behind the wheat Steeping and budding, be seeded into rhizoctonia solani (concentration 10
7Cfu/g) in the soil, after planting move on in the illumination box and cultivate, 22 ℃ of temperature, humidity 80 ~ 90% is observed the situation of emerging every day, 20 days " Invest, Then Investigate " diseased plant rate and seedling quality (comprising plant height, fresh weight, long, the radical of root) thereof
Wheat aphid: first with behind the Dressing behind the wheat Steeping and budding, be seeded in the soil with rhizoctonia solani, after planting move on in the illumination box and cultivate, 22 ℃ of temperature, humidity 80～90% treats that wheat length is to two leaves wholeheartedly the time, inoculate 100 aphids on wheat seeding, 7d " Invest, Then Investigate " borer population alive.
Table 1 composite insecticidal bactericide indoor measurement result
As can be seen from the table, MTI-446 and Tebuconazole single dose do not have the double effects of desinsection and sterilization.MTI-446 and Tebuconazole mixture preparation have obvious control efficiency to aphid and wheat damping off.Simultaneously, it is long that mixture preparation can significantly improve plant height, fresh weight and the root of wheat, shows that MTI-446 and Tebuconazole are mixed and rear wheat are had the effect in strong sprout, can improve the quality of wheat seedling.
